Q1:

Ferrite have

A low copper loss

B low eddy current loss

C low resistivity

D higher specific gravity compared to iron

ANS:C - low resistivity

Ferrite is a low density material of composition with Fe2O3 x O, where x is a bivalent metal, such as Cobart, Ni, Mn. These magnetic materials having very low loss of current and used in high frequency circuit.
